Faucet



Patented Nov. 21, 1933 UNITED STATES PATENT OFFICE FAUCET Louis Piro,Philadelphia, Pa.

Application June 15, 1932. 'Serial No. 617,365 1 Claim. 7 (01. 210-78)My invention relates to a novel and a useful faucet which is providedwith a self-cleaning internal strainer interposed between the intakepipe and the discharge outlet of the faucet in such a way that the waterpasses through a suitable screen, deposits its debris and sedimentthereon, and flushes clean the straining element at all times whileflowing.

My invention further relates to a faucet of this character wherein thedischarge outlet or nozzle member is of the rotatable and easilydetachable type to permit of ready removal and reinsertion of the screenfor repair or replacement.

My invention still further relates to a faucet wherein an easilyremovable plunger permits the escape of the accumulated debris andsediment through a by-pass under the pressure of the intake water.

My invention relates furthermore to a faucet wherein an easily removabletensioned plunger automatically permits the escape of the ac-' cumulateddebris through a by-pass when the strainer becomes clogged by the actionof the water under pressure forcing the plunger from its seat.

My invention relates also to several other outstanding features ofconstruction and convenience and all are hereinafter described andclaimed in connection with the accompanying drawing in which:

Figure 1 is a top view of a faucet embodying my invention.

Figure 2 represents a section on line 22 of Figure 1.

Figure 3 is a view showing details of construction of the strainer,

Referring to the drawing, in which like reference characters indicatelike parts, 1 represents an intake pipe of any suitable construction fordelivering water, said pipe being connected to a source of water in anydesirable manner. Intake 1 discharges the water into chamber 2 throughthe beveled orifice 3 of the said intake. Orifice 3 is carefullymachined to serve as a seat for the plunger valve 4 suitably designed toaccommodate itself closely to said orifice. Said plunger valve 4 isrigidly or integrally attached to the screw 5, said screw terminating ina stem 6 to which is attached the lever or handle '7. The stem 6 passestightly through the cap fitting 7, which threadedly engages the casing8, the inner surface of which is threaded to receive tightly the screw5. The stem 6 and screw 5 are designed to engage their separate fittingstightly or cleaning.

in order to prevent breakage of water past the stem 6. To the forwardend of the casing 8 is threadedly engaged the discharge outlet 9 whichis held securely in position by means of the lock nut 10. The inner endof the outlet is threadedfii) to engage the ferrule 11 over the innerend of which is spread a screen 12 of any desirable mesh. At the lowerend of the casing 8 and formed by the intake 1 and the bottom of saidcasing is the by-pass 13 which is ordinarily closed :6

'by the abutment of the plunger 14 against the beveled shoulder 15. Theplunger 14 is carried by the stem 17 which passes through the threadedfitting 18 and which is provided with the The fitting 18 threadedlyengages an ;.70

The operation of my novel faucet is described J5 briefly as follows.When the lever or handle '7 is rotated sufiiciently the screw 5 and theplunger valve 4 are lifted from the seat 3 permitting the water enteringthe intake 1 to flow into chamber 2. pinges against the strainer 12which separates the insoluble materials and prevents them from furtheronward movement and permits the clarified water to pass through its meshand thence through the discharge outlet 9. for the most part collects inthe by-pass 13 although some may persistently adhere to the strainer 12in spite of the intermittent flow of water through and the impact ofwater against it. To clean the strainer 12 and to purge the e!) Iby-pass 13 the knob 19 is pulled'outwardly, thus withdrawing the stem 17and the valve 14 to disengage the latter from its seat 15, thusestablishing communication between the passage 13 and the outlet 20.

spring 21 serves to return the valve 14 back to 7 its seat 15 when thepulling action on the knob 19 is discontinued. It is to be observed alsothat inexceptional cases when the strainer 12 becomes The water with itsdebris and sediment im-QO The sediment 7 The pressure of the helical 05excessively clogged with debris the pressure of the water in the chamber2 forces back the plunger valve 14 against the action of the spring 21and carries the debris through the by-pass 13 and the water outlet 20.

In order that the strainer 12 can be more thoroughly cleansed the locknut 10 can be loosened and the discharge outlet 9 can be withdrawn fromthe casing 8, thus permitting of an easy removal of the strainer 12 forrepair, replacement position, a ferrule threaded into the inner end ofsaid outlet, a screen carried by said ferrule to filter the waterpassing from said chamber to said outlet, a by-pass leading from saidchamber to a waste outlet, and a removable spring tensioned valve fornormally closing said by-pass, said valve being operable from withoutand being adapted to be actuated by the pressure of the water withinsaid chamber to establish communication betweensaid by-pass and saidwaste outlet.
